在JBoss EAP 6.3.0.GA（AS 7.4.0.Final-redhat-19）env

中使用c3p0 pooling'New missing/unsatisfied dependencies'錯誤我想將c3p0連接池集成到JBoss EAP 6.3.0.GA (AS 7.4.0.Final-redhat-19)到Mbean服務中。搜索了一些例子並嘗試將其整合。這是我的配置。添加c3p0罐子和module.xml成模塊DIR {JBOSS_HOME}/modules/system/layers/base/com/c3p0/main，module.xml配置：在JBoss EAP 6.3.0.GA（AS 7.4.0.Final-redhat-19）env

<?xml version="1.0" encoding="UTF-8"?> 
<module xmlns="urn:jboss:module:1.1" name="com.c3p0"> 
    <resources> 
     <resource-root path="c3p0-0.9.5.1.jar"/> 
     <resource-root path="c3p0-oracle-thin-extras-0.9.5.1.jar"/> 
     <resource-root path="mchange-commons-java-0.2.10.jar"/> 
    </resources> 
    <dependencies> 
     <module name="javax.api"/> 
     <module name="javax.transaction.api"/> 
    </dependencies> 
</module>

在standalone.xml加入c3p0到全球模塊（類路徑）：

<subsystem xmlns="urn:jboss:domain:ee:1.2"> 
    <global-modules> 
     <module name="com.c3p0" slot="main"/> 
    </global-modules> 
</subsystem>

新增服務文件到{JBOSS_HOME}/standalone/deployments/c3p0-service.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<server xmlns="urn:jboss:service:7.0" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="urn:jboss:service:7.0 jboss-service_7_0.xsd"> 
<mbean code="com.mchange.v2.c3p0.jboss.C3P0PooledDataSource" 
    name="jboss.jca:service=DataSourceBinding,name=jdbc/myDB"> 
    <attribute name="JndiName">java:jdbc/myDB</attribute> 
    <attribute name="JdbcUrl">jdbc:oracle:thin:@server.com:1521:sid</attribute> 
    <attribute name="DriverClass">oracle.jdbc.driver.OracleDriver</attribute> 
    <attribute name="User">username</attribute> 
    <attribute name="Password">password</attribute> 
    <attribute name="MaxPoolSize">20</attribute> 
    <attribute name="AcquireRetryAttempts">0</attribute> 
    <depends>jboss:service=Naming</depends> 
</mbean> 
</server>

推杆數據源配置分別從standalone.xml分成{JBOSS_HOME}/standalone/deployments/c3p0-ds.xml,ojdbc6.jar放置在相同的目錄。

<datasources xmlns="http://www.jboss.org/ironjacamar/schema"> 
      <datasource jta="false" jndi-name="java:/jdbc/myDB" pool-name="myDB" enabled="true" use-ccm="false" use-java-context="true"> 
        <connection-url>jdbc:oracle:thin:@server.com:1521:sid</connection-url> 
        <driver-class>oracle.jdbc.OracleDriver</driver-class> 
        <driver>ojdbc6.jar</driver> 
        <security> 
         <user-name>username</user-name> 
         <password>password</password> 
        </security> 
        <pool> 
         <min-pool-size>30</min-pool-size> 
         <max-pool-size>300</max-pool-size> 
         <prefill>true</prefill> 
        </pool> 
        <timeout> 
         <blocking-timeout-millis>120000</blocking-timeout-millis> 
         <idle-timeout-minutes>5</idle-timeout-minutes> 
        </timeout> 
        <validation> 
         <validate-on-match>false</validate-on-match> 
         <background-validation>false</background-validation> 
        </validation> 
        <statement> 
         <share-prepared-statements>false</share-prepared-statements> 
        </statement> 
       </datasource> 
       </datasources>

web.xml

<resource-ref> 
    <description> 
    </description> 
    <res-ref-name>jdbc/myDB</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref>

jboss-web.xml

<resource-ref> 
    <res-ref-name>jdbc/myDB</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <jndi-name>java:/jdbc/myDB</jndi-name> 
</resource-ref>

在部署結束我得到錯誤： New missing/unsatisfied dependencies: service jboss.mbean.service.jboss:service=Naming.create (missing) dependents: [service jboss.mbean.service."jboss.jca:service=DataSourceBinding,name=jdbc/myDB".create] service jboss.mbean.service.jboss:service=Naming.start (missing) dependents: [service jboss.mbean.service."jboss.jca:service=DataSourceBinding,name=jdbc/myDB".start]

我試過很多的MBean '名' 的變化屬性，但似乎是問題是在依賴...需要幫助我做錯了什麼。任何幫助將不勝感激！

EDIT: Found another approach which is described below.

使用的另一種解決方案如何c3p0連接添加到JBoss EAP 6.3.0.GA（AS 7.4.0.Final-的redhat-19，因爲標籤不JBoss上的7個工作（當我從this理解。話題）我使用的服務檔案（SAR）的方法首先，我們需要將c3p0模塊添加到JBoss與指定的JAR的（不記得是否需要所有JAR的）：

<?xml version="1.0" encoding="UTF-8"?> 
<module xmlns="urn:jboss:module:1.1" name="com.c3p0"> 
    <resources> 
     <resource-root path="c3p0-0.9.5.1.jar"/> 
     <resource-root path="c3p0-oracle-thin-extras-0.9.5.1.jar"/> 
     <resource-root path="mchange-commons-java-0.2.10.jar"/> 
    </resources> 
    <dependencies> 
     <module name="javax.api"/> 
     <module name="javax.transaction.api"/>  
     <module name="com.oracle.ojdbc6"/> 
     <module name="org.hibernate"/> 
    </dependencies> 
</module>

添加c3p0全球模塊到standalone.xml（如問題部分）添加數據源到standalone.xml

<subsystem xmlns="urn:jboss:domain:datasources:1.2"> 
     <datasources> 
      <datasource jta="false" jndi-name="java:/jdbc/myDB" pool-name="myDB" enabled="true" use-ccm="false"> 
       <connection-url>jdbc:oracle:thin:@server.com:1521:sid</connection-url> 
       <driver-class>oracle.jdbc.OracleDriver</driver-class> 
       <driver>oracle</driver> 
       <pool> 
        <min-pool-size>30</min-pool-size> 
        <max-pool-size>300</max-pool-size> 
        <prefill>true</prefill> 
       </pool> 
       <security> 
        <user-name>username</user-name> 
        <password>password</password> 
       </security> 
       <validation> 
        <validate-on-match>false</validate-on-match> 
        <background-validation>false</background-validation> 
       </validation> 
       <timeout> 
        <blocking-timeout-millis>120000</blocking-timeout-millis> 
        <idle-timeout-minutes>5</idle-timeout-minutes> 
       </timeout> 
       <statement> 
        <share-prepared-statements>true</share-prepared-statements> 
       </statement> 
      </datasource> 
      <drivers>   
       <driver name="oracle" module="com.oracle.ojdbc6"> 
        <datasource-class>oracle.jdbc.driver.OracleDriver</datasource-class> 
       </driver> 
      </drivers> 
     </datasources>

在部署創建文件夾，例如c3p0Pool.sar。創建META-INF文件夾{JBOSS_HOME}/standalone/deployments/c3p0Pool.sar/META-INF。此文件夾中創建jboss-service.xml文件的內容：

<?xml version="1.0" encoding="UTF-8"?> 
<server xmlns="urn:jboss:service:7.0" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
      xsi:schemaLocation="urn:jboss:service:7.0 jboss-service_7_0.xsd"> 
<mbean code="sar.C3P0PoolBinding" name="c3p0:service=c3p0Pool"> 
<attribute name="JndiName">jdbc/myDB</attribute> 
<attribute name="JdbcUrl">jdbc:oracle:thin:@server.com:1521:sid</attribute> 
<attribute name="DriverClass">oracle.jdbc.driver.OracleDriver</attribute> 
<attribute name="User">username</attribute> 
<attribute name="Password">password</attribute> 
<attribute name="MaxPoolSize">20</attribute> 
<attribute name="AcquireIncrement">0</attribute> 
</mbean> 
</server>

創建類和接口（類的名字應該被正確命名爲：類名和ClassNameMBean）：

package sar; 

import java.util.logging.Level; 
import java.util.logging.Logger; 

import javax.naming.NamingException; 

import com.mchange.v2.c3p0.jboss.C3P0PooledDataSource; 

public class C3P0PoolBinding implements C3P0PoolBindingMBean { 

    private String JndiName; 
    private String JdbcUrl; 
    private String DriverClass; 
    private String User; 
    private String Password; 
    private int MaxPoolSize; 
    private int AcquireIncrement; 
    private C3P0PooledDataSource c3p0; 

    public C3P0PoolBinding() {} 

    public String getJndiName() { 
     return this.JndiName; 
    } 

    public void setJndiName(String parameter) throws NamingException { 
     this.JndiName = parameter; 
    } 

    public String getJdbcUrl() { 
     return this.JdbcUrl; 
    } 

    public void setJdbcUrl(String jdbcUrl) throws NamingException { 
     this.JdbcUrl = jdbcUrl; 
    } 

    public String getDriverClass() { 
     return this.DriverClass; 
    } 

    public void setDriverClass(String driverClass) throws NamingException { 
     this.DriverClass = driverClass; 
    } 

    public String getUser() { 
     return this.User; 
    } 

    public void setUser(String user) throws NamingException { 
     this.User = user; 
    } 

    public String getPassword() { 
     return this.Password; 
    } 

    public void setPassword(String password) throws NamingException { 
     this.Password = password; 
    } 

    public int getMaxPoolSize() { 
     return this.MaxPoolSize; 
    } 

    public void setMaxPoolSize(int maxPoolSize) throws NamingException { 
     this.MaxPoolSize = maxPoolSize; 
    } 

    public int getAcquireIncrement() { 
     return this.AcquireIncrement; 
    } 

    public void setAcquireIncrement(int acquireIncrement) throws NamingException { 
     this.AcquireIncrement = acquireIncrement; 
    } 

    public void start() throws Exception { 
     Logger.getLogger(C3P0PoolBinding.class.getName()).log(Level.INFO, "Enabling c3p0 connection Pool"); 
     try { 
      c3p0 = new C3P0PooledDataSource(); 
      c3p0.setJndiName(JndiName); 
      c3p0.setJdbcUrl(JdbcUrl); 
      c3p0.setDriverClass(DriverClass); 
      c3p0.setUser(User); 
      c3p0.setPassword(Password); 
      c3p0.setMaxPoolSize(MaxPoolSize); 
      c3p0.setAcquireIncrement(AcquireIncrement); 
      c3p0.start(); 
     } catch (NamingException ex) { 
      ex.printStackTrace(); 
     } 
    } 

    public void stop() throws Exception { 
     Logger.getLogger(C3P0PoolBinding.class.getName()).log(Level.INFO, "Stopping c3p0 connection Pool"); 
     c3p0.destroy(); 
    } 
}

接口：

package sar; 

import javax.naming.NamingException; 

public interface C3P0PoolBindingMBean { 

    public String getJndiName(); 

    public void setJndiName(String JndiName) throws NamingException; 

    public String getJdbcUrl(); 

    public void setJdbcUrl(String jdbcUrl) throws NamingException; 

    public String getDriverClass(); 

    public void setDriverClass(String driverClass) throws NamingException; 

    public String getUser(); 

    public void setUser(String user) throws NamingException; 

    public String getPassword(); 

    public void setPassword(String password) throws NamingException; 

    public int getMaxPoolSize(); 

    public void setMaxPoolSize(int maxPoolSize) throws NamingException; 

    public int getAcquireIncrement(); 

    public void setAcquireIncrement(int acquireIncrement) throws NamingException; 
}

Finnaly ，用這些類創建JAR文件並將其放置到{JBOSS_HOME}/standalone/deployments/c3p0Pool.sar/c3p0Jar.jar

現在c3p0池應該按預期工作。
